Be it'knoivn that I, JOSEPH MoivRY; a citiz'e'nof the United States; and resident of Cleveland, in the county of Cuyahbga and State of Ohio, have invented certain nevv and useful Improvements combined Check and Globe Valves and Trinuner's, of which I hereby declare the following to be a full, cleaijand exact description, such as will enableo'thers skilled in the art'to which it a'ppertains' to make and use the same;

The invention relates to'theclass of valves; emplbyedijin work requiiing the use of fluids under high ressu e, and the objects are to provide means r f'acilitating cutting and r'egr'iiiding the'valve seat to produce perfectly" tight closure when the valve is closed, and the invention also includes a" combined globe and check valve which can be used interchangeably at the pleasure of the operator, that is itcanbe used as a check valve; or the check valve portion can be removed to permit the globe valve to be used;

ltalso'includes a check valve'whichcan be. regulated 'to'adjust the amount of flovv of "the fluid passing etherethrough.

The invention includes" means" i011 Gilli p'loy'ing a cutting dimming tool in lieu of the val es, to prepare the seat for the valve; and thecuttingftool'iv'ith the acconil y g' perating parts of the valve caii" be inserted in any valve casing of ordinary type and employed'to trimiitce and'renew new orold valve seats. f

The "invention comprises the combination f may arrangement with the" valveseat and casing and'iclo'sure therefor or plug, of

suitable valve and valve stem, and a' yoke or stem supporting ininbenvvhich is ad justable' upon said closure, for operating the'valvei V The devicelalso includes means forro mung 'said'yoke and or"sepmteiy-rotain said valvestem; J a I I I The inventita'incmdes a separate stem interchangeable vvith the valve stern and having a cutting or reaming tool adjustably attached thereto. The invention is illustrated in the'accomr ying d aw ng hQ -ne t rm m te ly described, and specifically pointed out in,

the claims.

Means are also provided for rotatingth'e" alv eit er, th h ck. orvtgl b ivelve 9 both of them, to regrind the seat so as to refinish it when it becomes Worn.

' the yoke lever K which is provided with oppositely extending lugs 11, L, which can alternatively be engaged with the marginal opening M, M in the disks H and J re spectlvely.

The pivotal shaft is preferably a rod 0 joining the arms 0 O of the yoke lever, and which can be removed so as to permit the lever to be withdrawn. By alternately engaging said yoke lever with said disks all the operations connected with the valve can be performed.

The lower portion of the yoke is split at S and the parts are connected by means of the eye bolt S v This connection forms a clamp by means of which the yoke is held from movement when adjusted to give the proper elevation of movement to the check valve. It also serves to retain the cutting tool in rigid position when used as will be hereinafter described.

I The cutter by means of which the valve In Figs. 1 and 2, a sleeve X is'shown which can be used as an extra collar or thimble to adapt the yoke and valveto a larger size of easing. v

The addition of a sleeve X permits the valve and yoke to be used interchangeably with casings of difierent sizes, so that it will be unnecessary to throw away used casings which are the heaviest and most valuable portions of the device, but the valve seat can be recut or trimmed therein and the casings will be as perfect as before, and the valve and seat can be made to perfectly correspond with each other.

Cutters can be provided that can be interchanged to correspond with any form of valve and seat, so as to utilize any old casings.

Copies of this patent may be obtained for seat therein, and provided with an exterior opening for the insertion of a valve, a closure for said openinghavlng a screw threaded outer extremity, a yoke adjustable thereon, a valve stem and valve thereon, mov- I able longitudinally with said yoke and revoluble therein, a lever rotatable about said stem and alternatively engageable therewith and with said yoke whereby said yoke can be rotated to adjust the position of said valve relatively to said seat and, alternatively therewith, said valve can be rotated upon said seat, substantially as described.

, 2. In combination, a casing provided with a valve sea'tand also having an external opening for the introduction of a valve, a closure for said opening, a rotatable yoke longitudinally adjustable upon said closure, clamping means therefor, a valve, a valve stem governing said valve longitudinally movable with said yoke, a disk upon said yoke'loosely surrounding said stem, a corresponding disk secured to said valve stem, and a lever alternatively engageable with said'disks, for alternatively rotating said yoke and stem, and means for attaching said lever in place, substantially as described.

3. In combination, a valve casing, a seat therein, said casing having an external opening, a closure therefor, a rotatable yoke longitudinally adjustable upon said closure, a valve, a valve stem governing saidlvalve longitudinally movable with and rotatably mounted in said yoke, means for alternatively engaging said yoke and valve stem to separately rotate the same, a second stem interchangeable[with the aforesaid stem,

and a seat cuttingattachment secured to said second stem and operable therewith, substantially as described.

4. In combination, a valve casing'having an exterior opening, a closure for said opening, a valve seat in said casing, a stem and valve, a rotatable support for said stem adjustable 011 said closure, said stem being rotatably mounted in said support, a second steminterchangeable with the aforesaid stem, a cutting tool adjustably secured to said second stem, means for clamping said stem support in adjusted position upon said closure, and a common means for alternatively'rotating the stem and the support.

'In testimony whereof, I hereunto set my hand this 14th day of December, 1914.
